Pros & Cons

👍 Pros

Co-extruded polycarbonate and deep dyed polyester construction resists fading and heat degradation
20" x 24" sheet is large enough to be cut to fit most standard stage lighting fixtures
22% transmission creates a rich, saturated color effect that adds dramatic depth to scenes
The deep amber with a blue touch produces a distinctive warm tone not easily replicated by mixing other gels

👎 Cons

22% transmission significantly reduces light output, requiring higher-intensity fixtures to compensate
Single sheet format means you will need multiple sheets for larger rigs or frequent replacements
No adhesive or frame included — requires separate gel frames or clips for mounting
Color name "Scarlet" may be misleading since the actual output is a deep amber rather than red

Frequently Asked Questions

What color does this Roscolux gel actually produce?

Despite the "Scarlet" name, this filter produces a very deep amber hue with a touch of blue, creating a warm, rich tone rather than a true red.

How durable is this gel filter under hot stage lights?

It is made from co-extruded polycarbonate plastic and deep dyed polyester, which are engineered to resist heat and fading better than standard polyester-only gels.

What does 22% transmission mean in practical terms?

It means the filter allows 22% of the light through, which is relatively low — expect a significant reduction in brightness, so you may need to compensate with higher-intensity fixtures.

Can I cut this gel to fit different fixture sizes?

Yes, the 20" x 24" sheet can be easily cut with scissors or a craft knife to fit standard ellipsoidal, par can, and fresnel fixtures of various sizes.

Is this filter suitable for LED fixtures or only conventional tungsten lights?

Roscolux gels are designed primarily for use with conventional tungsten and halogen fixtures. They can be placed in front of LEDs but are generally unnecessary since most LED fixtures have built-in color mixing.
